MACHINE FOR APPLYING MOUTHPIECE-FORMING SHEETS TO CIGARETTE-PAPER STRIPS.

' ident of Dresden, Germany, have invented tobacco, such which can readily mouth piece sheet.

certain new and useful: Improvements in Machines for Applying Mouthpiece-Forming Sheets to Cigarette-Paper Strips, of which the following is a specification.

My invention relates generally to machines,

for forming cigarettes by the continuous rod method, and is articularly directed to apparatusfor app ying to the strip of paper employed in such machines sheets of tip forming material at fixed intervals.

My general object has been to improve on the type of machine for this purpose which perates on the paper strip in advance of the point where it is'curled to receive the machines being adapted to cut from a continuous strip of mouth piece forming sheet material pieces of suitable size, and to apply such pieces to the cigarette wrapper strip at spaced intervals upon areas to which adhesive has been applied. The function of such machines is therefore three-fold; to pull a suitable amount of mouth piece strip from a roll; to cutoff the proper length; and to apply such length accurately t the moving wrapper strip.

- A- principal object of my invention is to simplify substantially theapparatus required for this purpose and provide a mechanism be actuated by the standard drive of cigarette machines.

More particularly, an important object is to provide such an -apparatus in which a single actuating element'having-a forward and return movement will suffice to operate all the moving parts of the device, which generally consist of a moving support, a cutter, and strip clamping means.

More specifically, my object also is to produce a 'mouth piece sheet applying apparatus which can be operated entirely by a device mounted on a single continuously rotating shaft, such as a crank or its equivalent.

A further purpose has been to devise a cutting and applying mechanism in which the mouth piece material may be drawn ofi' continuously from the supply roll, as distinguished from intermittent withdrawal thereof, without materially jamming or distorting the material in the cutting and applying apparatus.

Specification of Letters Patent.

Application filed October 5, 1921.

which Patented May 30, 1922. Serial No. 505,681.

Other objects, such as strength, compactness, ease of manufacture, ready replacement of parts, and the like, will be apparent from the following description taken 1n connection with the accompanying drawings, in

Fig. 1 is a somewhat diagrammatic side elevation of a referred form immediately subsequent to t and Fig. 2 is a similar view at a' slightl later stage of operation at which the cut s eet is applied to the cigarette wrapper strip.

In the preferred form illustrated, the entire apparatus is actuated through contmuously rotating shaft 1 carrying a crank disk-2 upon which crank pin 3 is mounted. The main frame comprises an bar 4 and a lower vertical arm 5, arm 4 being mounted onarm 5 in suitable guideways to slide longitudinally thereon. Bar 4 is pivotally mounted on the crank pin 3, while arm 5 is pivoted on stud 6 carried by a fixed portion of the cigarette machine frame.

The cutting mechanism compriseses. knife 7 mounted on bar 4, and cooperating with a knife 8 mounted on arm 5 to form shears extending transversely across the mouth piece strip 20.

In order to hold the severed portion of mouth piece forming material in position for accurate application to the cigarette wrapper strip, I provide means for clam ing such severed portion subsequent to t e cutting operation. For this purpose, I employ members mounted on bar 4 and arm 5, so arranged that when the bar approaches lowermost position, such members will cooperate to engage the advance portion of the mouth piece material. To this end I prefer to employ a fixed abutment and a yielding abutment, the form illustrated being provided with a clamp rod 9 mounted in a longitudinal guideway connected to bar 4, and movable vertically therein, spring 10 serving to yieldably retain the clamp in lowermost position. The fixed abutment or table 11 is mounted on arm 5 in register with clamp 9.

The strip of mouth piece material 20 is fed to the device by any preferred means the one illustrated comprising rollers 12 and 13, the shaft of the latter carrying a pinion l5 meshing with pinion 14 on shaft 1. The

e strip cutting operation.

upper verticalcigarette wrapper strip 18, after passing through suitable adhesivc-applying mechanism well known in this specific art and therefore not shown, passes downwardly and to the left about roller 17, any suitable pressure device such as roller 16 being preferably provided adjacent roller 17 to press the mouth piece sheet into forming engagement with the cigarette wrapper strip 18.

In the form shown roller 16 is slightly spaced from roller 17 in position to escape the application of adhesive in case no mouth piece sheet is fed, but sufficiently close to apply suitable pressure to the mouth piece sheet.

The operation of the machine is as follows. As shaft 1 rotates in a clockwise direction, crank pin 3 alternately raises and lowers cutter knife 7 and clamp 9. It also oscillates bar 4 and arm 5 about the pivot (i, producing the feeding movement of the apparatus.

Starting with crank pin 3 in its uppermost position, with clamp 9 and knife- 7 above the plane of the mouth piece sheet strip 20, rollers 12 and 13 feed the advance end of such strip over knife 8 and onto table 11, while the apparatus is swinging to the right as pin 3 descends. At about the time when the pin is at the limit of its movement to the right, or sufficiently thereafter to prevent uneven pull on the strip 20, clamp 9 presses the advance end of strip 20 onto table 11, and knife 7 commences to sever the strip The continued descent and advance of pin 3 completes the severing, the knife 7 advancing as strip 20 is fed forward by rolls 12 and 1 to prevent bucklingof the strip, and at the same time feeding the severed sheet 19 forward toward roll 17. This position is shown in Fig. 1.

The continued advance of the pin feeds sheet 19 between rollers 16 and 17 into engagement with the adhesively coated portion of the wrapper strip 18, roller 16 serving to insure thorough engagement between the sheet and strip. At the same time knife 7 rises. and after spring 10 has expanded to the limit permitted, clamp 9 also ascends, permitting rollers 12 and 13 to continue the feed of the strip 20 while pin 3 is swinging from its upper left-hand position to its upper right-hand position about the axis of shaft 1, whereupon the above operation is repeated.

It will be apparent that many variations in the timing of the clamp and knife actions can be employed without departing from my invention. Furthermore, while I have indicated a convenient and obvious method of mounting the knives and clamping apparatus, this may be varied Within wide limits.

I have shown my invention as applied to a continuous feed for the mouth piece forming strip; but my invention is not necessarily limited thereto, though it solves the problem of operation with a feed of this type. In particular, it has heretofore been proposed to employ a reciprocating table with a vertical cutter operating at an intermediate portion thereof, with clamps both in advance and to the rear of said cutter. sothat the device operates as an intermittent feed. I consider my invention to be applicable to any variations of this or other types which will be apparent to those familiar with this art.
